I've never provided a recipe as I don't tie that much, so I'm not sure how best to describe it, but I'll try.
All the material is slinky fiber and krystal flash. The main object when you're tying is to have the bottom of your fly white, and the top dark.
I tie in a white beard on the bottom of the fly first, trim it somewhat short to avoid getting fouled in your hook. When you tie it on to the tube, tie it in halfway up the tube. You should have roughly an equal amount of slinky fiber sticking forward as you do backwards, when you put the conehead on later it will force the fiber sticking forward towards the back. Make sure your fiber is not all trimmed the same length, pull some fibers out longer so it has a more organic look.
Next I tie in some more white slinky fiber on the top, I also add my flash. I trim the forward facing fibers off rather then have them pulled back when I put the conehead on.
Next tie in a mixture of different colored fibers, leave this pointing forward like the beard. Then last I shove my conehead over the tube which folds back the forward facing beard on the bottom, and also pushes back the colored forward facing fibers on the top. Again make sure your fibers are not uniform in length.
Trim the tubing above the conehead to about 1/8th of an inch, then take a lighter and melt the end of the tube, that will anchor the conehead against the thread base that you tied in the middle of the tube. This is the trickiest step for me, I end up burning my fingers trying to hold the conehead against all the fibers/thread base while melting the plastic.
Take your epoxy and try and fill the backside of the conehead up, this should cement your thread base and help the general endurance of your fly. I usually tape the back of the flies to my desk and let them dangle down to dry. This is a nice patter because you don't need a rotating disk to dry your epoxy.
Some things to remember, don't let your fibers be uniform length, trim them at random lenghts, they look more lifelike. Make sure and leave enough room for yourself to slide your conehead on. THe first couple I tied I had to start over because I did not tie everything on in the middle of my tube.
I picked up the pattern from Anil at puget sound fly co, if you're in the area talk to him, he could probably give you a better description on how to tie them up.
